Most of the studies only look at CO2-equivalent GHG emissions, but when you factor in other environmental pollutants like NOx, SO2, and fine particulate matter, it’s not even close to a modern internal combustion engine with modern emission controls.

Alberta, for example, has limits of:
0.8 kg/MWh for SO2, 0.69 kg/MWh of NOx, and 0.095 kg/MWh of PM2.5 on NEW power generating units, but existing infrastructure is allowed to operate until it’s 50 years old, so some plants will still be allowed to operate until the 2040s (under existing legislation) and those plants were built with much less stringent environmental regulations.

Meanwhile, a modern gasoline ICE engine has limits of 0 SO2, 3 mg/mile PM2.5, 125 mg/mile NMOG+NOx for Tier 3 bin 125 (which is the most common emissions standard for passenger vehicles).

If one assumes 400 hours of operation per year and 12000 miles per year (average 30 MPH/50 km/h) and average 40 hp (0.029828 MW) = 11.9312 MWh per year, 0.036 kg/year of PM2.5, 1.5 kg/year of NMOG+NOx

That’s 0 kg/MWh of SO2, 0.003 kg/MWh of PM2.5, and 0.126 kg/MWh of NMOG+NOx compared to 0.8, 0.095, and 0.69 respectively for NEW (not existing) coal-fired plants. 32x higher PM2.5 output and at least 5.5x higher NOx output per MWh
